Question

If the angles of a triangle are in the ratio 1:4:5, find the angles. Please answer it rn!​

Answer 1

Answer:

given,

angles of triangle are in ratio 1:4:5,

i.e,x,4x,5x.

we know that,

sum of the angles in triangle are 180°,

=> x + 4x +5x = 180°,

=> 10x = 180°,

=> x = 18°.

Therefore, the angles are 18°,72° and 90°.

Answer 2

Ratio 1:4:5

i.e x,4x,5x

sum of triangles are 180°

= x+4x+5x =180°

=10x=180°

x=18°
